DURHAM, N.C. - Rivals.com national analyst Mike Farrell breaks down five things we learned from the Nike camp at Duke on Sunday.

1. Azubike could blow up

We've been hoping to see Nashville (Tenn.) McGavock defensive end Caleb Azubike in person this spring. First he was going to attend the VTO camp in Georgia and then the Nike camp in Athens but he wasn't able to make either. And although we saw him at the Ultimate 100 camp in Nashville a year ago, we had heard he was bigger, stronger and better.

Finally he showed up, unannounced and somewhat unexpected, at the Duke camp. Wearing jersey No. 479 with no name on the back as a walk-up registrant, it wasn't until the full roster was handed out that it was clear that Azubike was there.

While he has early offers from Vanderbilt, Boston College and Kentucky, there is a chance things could blow up for Azubike in the next few months. Miami has apparently offered him now and that offer could bring many others.

2. Future linebackers

A few of them were playing out of position like future North Carolina likebacker Phillip Williamson (played defensive back), North Carolina defensive end Jamal Marcus (played defensive end but looks more like a 'backer) and massive Jay Jay McCullough from Fort Mill (S.C.) Nation Ford (played wide receiver). Many of them were where they belonged, but there was an abundance of future linebackers in attendance including many underclassmen.

Coleman was the running back MVP while the others all did well at their respective positions. Frye projects as a safety for Virginia Tech and McKinnon is likely to play the WHIP position. Greene is expected to be a cornerback.

5. North Carolina speed

Wide receiver Kedrick Davis was at the camp fresh off a 10.47 100-meter time in the 2A track and field championships on Saturday, finishing first. Teammate and fellow wide receiver Germone Hopper ran a 10.68 (third) and running back Todd Gurley ran a 10.71 (fifth). Gurley also won the 110 hurdles while Davis and Hopper finished third and fourth in the 200 meters, respectively, as well. Throw in running back Keith Marshall, who wasn't at the camp but runs a sub-10.5 100 meters, and the state of North Carolina is loaded with speed for the class of 2012.
